Fix terminal quick fix bugs

[meganrogge]

Fixes at least two cases of #211857

Previously, both the Create PR and Push Upstream terminal quick fixes required the command line to match a specific regex:

vscode/src/vs/workbench/contrib/terminalContrib/quickFix/browser/terminalQuickFixBuiltinActions.ts

Line 12 in 7de10c3

export const GitPushCommandLineRegex = /git\s+push/;

However, in certain cases, the captured commandLine was incorrectly set to gitpush instead of git push. This occurred when the user entered git and push on separate lines — such as when a command wrapped due to line length.

During the execute phase, the command was correctly recognized. But by the finished phase, the space had been lost, breaking the match:

The issue was caused by prematurely trimming whitespace before combining wrapped lines — which accidentally removed the space between command parts. We now apply trim() after assembling the full logical command line:

vscode/src/vs/platform/terminal/common/capabilities/commandDetectionCapability.ts

Line 544 in 7de10c3

currentCommand.command = this._hooks.isCommandStorageDisabled ? '' : this._terminal.buffer.active.getLine(currentCommand.commandStartMarker.line)?.translateToString(false, currentCommand.commandStartX, currentCommand.commandRightPromptStartX);

This resolves the previously reproducible git push failure case. It may also fix additional command-wrapping issues that previously failed to match the expected regex.
